If teleportation actually existed, then I would never use it.
When they made Star Trek, they forgot an important detail. As soon as you disassemble a body into millions of tiny particles, the person is dead. Even if you perfectly reassemble the body after teleporting the particles to their new destination, the person will still be dead. All you would have left was a perfectly assembled corpse.
Beam me up Scotty! Quantum teleportation of a particle of light six kilometers
What if you could behave like the crew on the Starship Enterprise and teleport yourself home or anywhere else in the world? As a human, you're probably not going to realize this any time soon; if you're a photon, you might want to keep reading. Ref. Source 5k.
Rasputin, I would have to disagree with you. We don't know how consciousness is generated or where it is carried in the brain. If you remove some small part of the brain, the underlying person doesn't necessarily change, but if they have a stroke and the brain doesn't get oxygen for a while, then the entire personality can change, with no noticeable change in structure. Who is to say whether teleportation would be able to transfer our consciousness to our new body or not. People can be 'brain dead' one moment and then come back to life the next. I think this is exciting new technology that needs to be explored. And even if people can never teleport, if we could only teleport objects, that would be a great step forward and enable lots of benefits.
Teleportation, I just don't see it as a reality, at least not anytime soon to compare it with the Star Trek movie. I believe consciousness is just electrical signals. RAM needs electrical power to 'memorize' anything… the same applies. Just think how much data can travel across electricity. Manipulating that will further our ability to 'teleport' anything if that ever happens.
